Pre JYM does not mess around…. 26.5 g per serving! That’s a big-ass scoop… but that’s also what it takes to hit Critical Mass Dosages for pre-workout benefits.

The formula’s ingredients are, for the most part, skillfully chosen and presented in strong dosages. Let’s check them out:

CarnoSyn® Beta-Alanine 2 g

Pre JYM bills this branded form of Beta-Alanine as the main ingredient, even though it’s not the biggest dose on the label. We can’t blame them.

Beta Alanine is a balls-out performance-enhancer for intense training, shown to increase number of repsbefore failure at the weights and lengthen time to exhaustion during cardio… it’s a hardcore muscle builder.

Pre JYM’s CarnoSyn® is a premium Beta Alanine form that’s easier for the body to tolerate and use in high doses.

Creatine 2 g (as Hydrochloride, or HCL)

Creatine is a must-have in any pre-workout formula. Pre JYM’s use of Creatine HCL is a sign of quality; the HCL makes it easier to absorb and more bioavailable, so more reaches your bloodstream and is distributed to your muscles.

You know the rest once creatine gets into those muscles: More explosive power, more reps, better gains.

Citrulline Malate 6 g

Another great pre-workout compound here. We’re impressed by the HUGE 6 g dose of Citrulline Malate found in Pre JYM. That’s more than what you’ll find in most other pre workout formulas.

With this hefty dose, Pre JYM supplies some professional-strength nutrition for muscle energy spikes in the gym and accelerated protein synthesis afterwards. Can you say “massive gains”??

BCAAs (Branched Chain Amino Acids)

BCAAs feature rapid uptake into muscle tissues, where they spark protein synthesis that leads to big gains. They also give a nice energy bump in the gym.

Beet Extract + Betaine (2 g total)

These beetroot-sourced pre-workout ingredients offer a 1-2 punch of muscle-priming activity: They increase nitric oxide for better muscle circulation and energize muscles for explosive lifts. They also improve muscle tissue synthesis… which is helpful, but not the main draw.

N-Acetyl Cysteine (NAC) 600 mg

Pre JYM talks mostly about NAC’s ability to increase endurance. They neglect to mention that NAC boosts the super-antioxidant enzyme glutathione, which protects muscles against the oxidative stress generated by high-intensity training.

600 mg is standard serving size of standalone supplements; it’s cool that Pre JYM includes a full therapeutic dose, so you don’t have to buy it separately.

Taurine 1 g

Pre JYM bills the Taurine as a nitric oxide-booster. It’s just OK for this purpose when combined with Arginine, which is absent—though the Citrulline in the formula can raise Arginine levels naturally, too.

Taurine seems like a weird ingredient choice for Pre JYM; there are better NO boosters that could have been used here.

Nootropic Boosters?

Pre JYM tries to address the mindset of mental dominance that can really supercharge athletic performance… but their nootropics fall short:

AlphaSize® Alpha GPC: Decent, not great, for focus & mental clarity

Huperzine-A: Fast acting for brainpower, but 50 mcg dose is WAY low

L-Tyrosine: Big 1.5 g, great for stress, but wrong form (Acetyl-L is better)

Nootropics are Pre JYM’s only real formula fumble. These 3 won’t do much for mental dominance. So if you’re looking for those kind of benefits, consider combining Pre JYM with a real nootropic formula.

Caffeine Anhydrous 300 mg

Damn, that’s a big dose of caffeine! It may work synergistically with some of the other ingredients, too… so there’s the potential here for aggression, jitters, irritability, etc… as well as potential for euphoric, over-stimulated super-strength. Be careful with caffeine in this high dosage.

Bioperine® 5 mg

Patented black pepper extract. This is an awesome ingredient because it boosts the absorption of other nutrients, so it can actually supercharge the entire formula. As a bonus, Bioperine supplies thermogenic activity that can help with fat-loss during your cutting phases.

Formula Analysis

Pre JYM is a quality formula with premium ingredients. It’s not quite as complete as claimed, but still delivers powerful results.

Pre JYM talks a lot of smack about their doses, but look closely and you see language like “full doses” and “powerful doses.”

This is not the same as “clinically backed dosages,” which becomes painfully obvious with Pre JYM’s nootropics. But that’s OK. Nootropics are not the main event.

When it comes to the core pre-workout compounds, Pre JYM brings you several of the best, some of which are in super-strength doses.

Plus, it seems designed to boost physical performance across many pathways, by leveraging a wide range of synergistic nutrients. This is another sign of smart formulation and results-oriented quality.

Pre JYM Benefits

Pre JYM is claimed to improve your workouts with “the most complete pre-workout formula available.” It is designed to prime your body for intense exertion—which they say will deliver “unreal results” for improving speed, strength, muscle-building and fat-burning.

Pre JYM’s claims check out: It’s formulated with some of the best ingredients for pre-workouts, and achieves its mission of providing them in one canister for both convenience and cost-effectiveness.

Who Takes It?

Anybody can take it… but we bet Pre JYM is a favorite of bro scientists. Pre JYM formulator Jim Stoppani is a Ph.D. bodybuilder who knows his stuff. The formula is based in real science, and draws athletes and gym rats looking for compounds and dosages that match up with clinical research.

Any Side Effects?

That would be a “Hell yeah.” Pre JYM is designed with quality ingredients, including synergistic combos and bioavailable patented ingredients where “less is more.” This suggests excellent tolerability and few side effects.

BUT, the one big red flag is that massive 300 mg dose of caffeine. Anticipate jitters with this formula. Really, before you buy it, be sure to read the Pre JYM label’s ominous warning about caffeine-related side effects.

Does Pre JYM Work?

Oh yes, it works. There’s a ton of positive feedback and rave reviews for Pre JYM. More importantly, the formula is great. It puts you in beast mode, but also gives you what you need to build mass and recover fast.
